The sensor includes a plurality of porous elements, a number of electrically conductive interface plates which is one greater than the quantity of elements, and the same number of conductors. Each element operates as a discrete variable capacitor, exhibits a different known liquid release curve, and includes a first axial opening. The elements are stacked one on top of another. Each plate includes a second axial opening. The plates are axially distributed within the sensor such that the first and second axial openings combine to form a longitudinal cavity that extends from the sensor's proximal end to its distal end, and each element is sandwiched between a different pair of plates. A distal end of each conductor is attached to a different one of the plates, and a proximal end is routed through the cavity to the sensor's proximal end."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stacked sensor for testing a porous medium","description":"A sensor is provided for testing a porous medium.
